At West Ham, Big Brother is always watching. Well, Big Sam is always watching, at least.

The West Ham manager revealed that every training session is filmed and the footage immediately downloaded to laptops for the medical team to monitor the players’ performances.

It can reveal if players are going out when they shouldn’t be and helps keep the younger ones on the straight and narrow.

Allardyce said: ‘We always ask players to do the right things. They are not always going to be angels but when they get monitored at the club there are signs. We download training live every day and, if there is a dip in form, we can ask the player what’s wrong, or was it a great night out?

‘It could be toothache, it could be flu, it could be anything. That’s one good thing about the technology. If you spot something you can intercept it. It’s expensive but worth it.’

One player he is paying particularly close attention to is Ravel Morrison. Allardyce, 58 - who celebrated 100 games at West Ham this month - has been astounded by how quickly the young midfielder has advanced since he returned from a season-long loan at Birmingham.

At the start of this campaign he warned his other central midfielders to be looking over their shoulders. A month later the 20-year-old has scored three goals in six games.

Allardyce joked it was his job to make sure the club didn’t need to fit larger doors for Morrison’s head to fit through. But he said more seriously that it is important he keeps the youngster’s feet on the ground, especially given his troubled past at Manchester United which hampered his talent. The technology at West Ham is helping him do that.

‘It’s just a warning,’ Allardyce added. ‘We know some of the lads like a night out. But it has to be at the right time.

Crock star: Andy Carroll is struggling to recover from a foot injury picked up from last season

‘It’s not like my day when the old pros used to sneak out for a few pints down the local and then sneak back in. You go to sleep and play the game the day after, that doesn’t happen any more.’

Hammers striker Andy Carroll has turned to renowned Belgian physiotherapist Lieven Maesschalck in a bid to recover from his heel injury.

Carroll said his body was in ‘bits’ after a week of exercises with the man credited for getting Manchester City’s Vincent Kompany back to fitness in time for the Premier League run-in after a calf injury in February.
